This is old... Remember the huge Tsunami in December of 2005 (?) in the indian ocean. Well all of these fish washed up because of that. I remember seeing these same pictures whenI was in 4th grade... no lie.

Essentially the only animals in that photo which are relatively "Prehistoric" would be the giant isopod, the squid, mind you the prehistoric version had a shell. The crab, well sort of, but not those shown. There were two varieties of shark, but it isn`t known how long they`ve existed in that form as they are ultra deep species.

The only marine animals who have not changed since prehistoric times are the chambered nautilus, the Coelacanth, and an argument could be made for the Carcharodon sharks.

Except for maybe #14, pretty much all of these are modern day fish. Some of them are just found really really deep, like the anglerfish, so we aren`t used to their appearance or they are transparent since there is very little light down there. But that doesn`t make them prehistoric.

After all, a shark is prehistoric. They have been around as long as dinosaurs. But we are used to them because they are found in the same depth that we typically swim or go fishing, so we see them all the time. At least I do.
